The signage at the start was inadequate. Haven't seen it since the crash over the side Monday morning, but up until that point it still was a little thin. It's one of those speed limits you actually have to abide by if you're in a larger vehicle. Little cars - no problem, you can probably take that corner at 60mph. The trucks that crashed were only doing 10mph over the limit... that 10mph was deadly.
The experience going inbound is also different from outbound. Inbound also appears to be where the accidents are. Inbound, you don't really see the corner until you're about to hit it due to the crest on the bridge.
I'm not sure why they don't put rumble strips, big flashing signs & light up the corner with lots of < < < < < < < < signs. I know country roads with better signage.
I'm not taking the responsibility away from the drivers - just speaking from personal experience here.
Yeah, a bunch of idiot measures are necessary. Without fully understanding the need for S-Curve and the alternatives, I just think it is a horribly design road section and the amount of accidents had to be expected.
